Protest videos against a proposed third runway at Heathrow Airport "bowled" over organisers with their "quality" and "passion", with the winner walking away with £10,000 in prize money.

The 'No Ifs No Buts' film competition grand finale was staged at Richmond Theatre on Wednesday (June 18), with the 16 hopeful short videos being screened before a celebrity judging panel that included Hugh Grant, Holly Willoughby, Gyles Brandreth and Rachel Johnson.

Zac Goldsmith, MP for Richmond Park, organised the event. He said: “I’m bowled over by the quality of these film submissions and am so grateful to all the entrants for all their hard work.

"It was tough for the judges, but we have very worthy and brilliant winners.

"Under the Labour government, the campaign against the third runway attracted the biggest, most diverse coalition ever assembled against airport expansion.

"It included politicians of all parties, economists, local residents, business people, trade unionists, environmentalists and direct action activists.

“If the government gives a green light for Heathrow expansion, that extraordinary campaign will roar back to life.

"The arguments against it are overwhelming, and the movement against it means the third runway simply cannot be delivered.”

The campaign was born following remarks made by Prime Minister David Cameron when he said a third runway at Heathrow was "not going ahead, no ifs, no buts".

However, within 30 months of taking power he set up the Airports Commission to look again at the question of a new runway.

On Wednesday night, around 800 people packed into Richmond Theatre to watch and judge the best films reminding Mr Cameron of his promise.

The winning entry, titled 'Heathrow Won't Listen', was made by Dan Grant, Andrew Chan and Tom Murray, featuring a family's enjoyment of some cherished time together being interrupted by the scream of jet engines above, but carrying on as normal as they had become so used to the din created by passing planes.

The runner-up, which won £3,000, was 'Say NO' by Kevin Jarin and Jacob Green - a Pixar-style computer animation depicting homes being destroyed to clear the way for an expanded Heathrow.

Third place and taking home £2,000 was 'Life Under The Flightpath' by Gabor Eszenyi, which returned to the theme of noise but turned it on its head in a parody extolling the virtues of living in a noisy environment.

John Stewart, chairman of the Heathrow Association for the Control of Aircraft Noise (HACAN), said: "Many congratulations to the winner. It is a great video.

"The competition highlighted once again the widespread and passionate opposition there is to a third runway at Heathrow.”

Commenting on the alternatives to Heathrow expansion, Mr Goldsmith said: “Freeing Gatwick from the old monopoly has brought real benefits to passengers, and cobbling it together again in a vast, foreign-owned and taxpayer-subsidised monopoly would be truly a retrograde step.

"We should invest in improving London’s surface connections, maximising rather than suffocating competition between three main airports.”
